This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 100144027 filed in Taiwan, R.O.C. on Nov. 30, 2011, the entire contents of which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Technical Field

This disclosure relates to a card reader for an electronic card, and more particularly to a card reader having movable card insertion mechanism and an electronic device having the movable card insertion structure.

2. Related Art

An electronic card such as a PCMIA card, PC Express card, flash memory card (CF, SD, Memory Stick, xD-Picture), or micro-drive, has a flat contour and has an electrical connector disposed at a side edge.

For connecting the electronic card to an electronic device, the electronic device is typically equipped with a card reader of the corresponding specifications. For example, U.S. Pat. No. 6,724,622 discloses a card reader. The card reader includes an electrical connection socket and a guiding element disposed on a circuit board of the electronic device and the card reader is located corresponding to an insertion hole in the case body of the electronic device. A guiding channel is formed between the guiding element and the circuit board, for ensuring the insertion hole is in communication with the electrical connection socket. When an electronic card is inserted through the insertion hole, the guiding channel guides the electrical connector of the electronic card to be inserted into the electrical connection socket, so as to establish communication between the electronic card and the electronic device.

The guiding channel is formed between the guiding element and the circuit board, for guiding the electronic card to be inserted into the electrical connection socket in a right way. In the card reader, only the electrical connector is actually finally electrically connected with the electronic card, but for forming the aforementioned guiding channel, the electrical connection socket is disposed at a distance from the insertion hole, so the card reader occupies a large area on the circuit board, thus influencing the arrangement of other electronic parts.

The US Patent Publication U.S. Pat. No. 7,448,890 discloses an electronic card and a card reader configuration, in which a width of the electrical connector of the electronic card is smaller than a width of the electronic card, but the guiding channel between the guiding element and the circuit board is still required to be larger in width than the electronic card. Although the width of the electrical connection socket of the card reader is reduced along with the width of the electrical connector, the card reader still occupies a large area on the circuit board.

DETAILED DESCRIPTION

Please refer to FIG. 1, FIG. 2 and FIG. 3, in which a card reader 100 having a movable card insertion structure according to a first embodiment is disclosed. The card reader 100 is disposed in a case body 900 a, 900 b, 900 of an electronic device 1 and is adapted for connecting an electronic card 800. The case body 900 has an insertion hole 910 for an electrical connector 810 of the electronic card 800 to pass through to be inserted into the card reader 100. The electronic device 1 includes at least one circuit board 930 disposed in the case body 900, and the card reader 100 is electrically coupled to the circuit board 930 to establish a signal communication between the electronic device 1 and the electronic card 800. The circuit board 930 usually is a main board or motherboard of the electronic device 1. In at least one example, the circuit board 930 is disposed independently and electrically connected to the main board/motherboard by a cable.

As shown in FIG. 1 and FIG. 2, the card reader 100 includes an electrical connection socket 110, at least one guiding member 120, at least one guiding rail 130, and a cover 140.

As shown in FIG. 1, FIG. 2 and FIG. 3, the electrical connection socket 110 is disposed in the case body 900 and is electrically connected to the circuit board 930. In the first embodiment, signal pins of the electrical connection socket 110 are soldered to electrical contacts of the circuit board 930, so that the electrical connection socket 110 is fixed on the circuit board 930 and meanwhile electrically connected to the circuit board 930, such that the card reader 100 inserted into the electrical connection socket 110 is electrically coupled to the circuit board 930. In some other examples of this disclosure, the electrical connection socket 110 is fixed on an inner side surface of the case body 900 and electrically connected to the circuit board 930 by a cable.

As shown in the figures, the electrical connection socket 110 is used for inserting the electrical connector 810 of the electronic card 800, so as to electrically connect the electronic card 800 to the electrical connection socket 110. The electronic card 800 includes, but not limited to, a PCMIA card, a PC Express card, a flash memory card (CF, SD, Memory Stick, xD-Picture), and a micro-drive (Micro-Drive).

As shown in FIG. 1, FIG. 2 and FIG. 3, the guiding member 120 is disposed in the case body 900 and is disposed to be corresponding to the electrical connection socket 110. The guiding member 120 provides a guiding slot 129 extending along a guiding direction X. The guiding direction X is parallel to a direction in which the electrical connector 810 is inserted into or unplugged from the electrical connection socket 110.

As shown in FIG. 4, in detail the guiding member 120 includes a first sidewall 121, a second sidewall 122, and a third sidewall 123. The second sidewall 122 and the third sidewall 123 respectively extend from the first sidewall 121, so that the guiding slot 129 is formed between the first sidewall 121, the second sidewall 122, and the third sidewall 123.

As shown in FIG. 4, FIG. 5, FIG. 6, the guiding rail 130 includes a sliding portion 131 and a lower support portion 132. The sliding portion 131 is disposed in the guiding slot 129 in a slidable manner to slide to-and-fro along the guiding direction X towards the insertion hole 910, so that the guiding rail 130 slides between a receiving position R and a card insertion position I. When the guiding rail 130 is at the receiving position R, the guiding rail 130 is accommodated in the case body 900. When the guiding rail 130 slides from the receiving position R to the card insertion position I, the guiding rail 130 moves towards the insertion hole 910. In one example of this disclosure, when the guiding rail 130 is at the card insertion position I, at least a part of the guiding rail 130 extends to the exterior of the case body 900 through the insertion hole 910.

The lower support portion 132 extends from the sliding portion 131, and is against a bottom surface of the electronic card 800 so as to support the electronic card 800. When the guiding rail 130 is at the card insertion position I, the sliding portion 131 and the lower support portion 132 guide the electronic card 800 to enter into the case body 900 through the insertion hole 910. Then the electronic card 800 is inserted into the electrical connection socket 110. Meanwhile, the lower support portion 132 also supports the electronic card 800 to avoid vibration of the electronic card 800 that may damage the electrical connection socket 110 or the electrical connector 810.

In one example, the guiding rail 130 further includes an upper support portion 133. The upper support portion 133 also extends from the sliding portion 131 and is parallel to the lower support portion 132. A clamping slit 134 is formed between the lower support portion 132 and the upper support portion 133. The clamping slit 134 just allows a side edge of the electronic card 800 to slide therein, thereby reducing the probability of the vibration of the electronic card 800. When the sliding portion 131 is disposed in the guiding slot 129 in a slidable manner, the clamping slit 134 also extends along the guiding direction X.

Generally, a single guiding rail 130 to guide and support a side edge of the electronic card 800 is sufficient for guiding the electrical connector 810 to pass through the insertion hole 910 to be inserted into the electrical connection socket 110 and providing the appropriate supporting force. Consequently, one guiding member 120 in combination with one guiding rail 130 is sufficient for guiding and support the electronic card 800. If two opposite side edges of the electronic card 800 are provide guided and supported simultaneously, the reliability of the card reader 100 is further guaranteed. Therefore, in one example, the card reader 100 includes two guiding members 120 and two guiding rails 130 for guiding and supporting two opposite side edges of the electronic card 800 at the same time.

As shown in FIG. 4, in detail the sliding portion 131 leans on the first sidewall 121, so that two opposite edges of the sliding portion 131 are respectively limited by the second sidewall 122 and the third sidewall 123, and the guide sliding portion 131 slides along the guiding direction X towards the insertion hole 910. Meanwhile, the upper support portion 133 and the lower support portion 132 respectively lean on the second sidewall 122 and the third sidewall 123.

Furthermore, the guiding member 120 further includes a guiding slit 125 formed on the first sidewall 121 and extending along a direction parallel to the guiding direction X. A first end 125 a of the guiding slit 125 is corresponding to the insertion hole 910, and a second end 125 b is distal from the insertion hole 910. The first end 125 a is opened while the second end 125 b is closed. The guiding rail 130 further includes a limiting pin 135 and a positioning pin 136, which are disposed on the sliding portion 131 for sliding in the guiding slit 125. The positioning pin 136 further protrudes to the outside of the first sidewall 121. A relative position of the limiting pin 135 and the positioning pin 136 is that the positioning pin 136 is near the insertion hole 910 and the limiting pin 135 is distal from the insertion hole 910. Furthermore, a positioning groove 125 c is further formed at a position, of the guiding slit 125, near the first end 125 a.

As shown in FIG. 4, FIG. 5, FIG. 6, when the guiding rail 130 is at the receiving position R, the limiting pin 135 presses against the second end 125 b of the guiding slit 125, so that the guiding rail 130 does not move towards the interior of the case body 900 further. When the guiding rail 130 is at the receiving position R, the positioning pin 136 is embedded in the positioning groove 125 c, so that the guiding rail 130 does not slide further.

As shown in FIG. 1, FIG. 2, FIG. 5 and FIG. 6, the cover 140 is pivoted to the guiding rail 130, and for closing the insertion hole 910. In one example, the cover 140 is connected to the positioning pin 136 in a rotatable manner, so as to rotate to open or close the insertion hole 910.

Furthermore, an engaging notch 141 is further disposed at the edge of the cover 140 and the guiding rail 130 further includes an engaging pin 137 adapted to be embedded in the engaging notch 141, so that the cover 140 remains in a closing state the insertion hole 910.

The relative position of the engaging pin 137 and the positioning pin 136 is that the engaging pin 137 is near the insertion hole 910 and the positioning pin 136 is distal from the insertion hole 910. When the guiding rail 130 is at the receiving position R, the engaging pin 137 passes through the first end 125 a of the guiding slit 125 to be embedded in the positioning groove 125 c. The engaging pin 137 further protrudes to the outside of the first sidewall 121. Thus, the cover 140 can be rotated to the closing state for closing the insertion hole 910, and the engaging pin 137 is embedded in the engaging notch 141 to fix the cover 140.

Please refer to FIG. 5 and FIG. 7, in which when the electronic card 800 is not connected to the electronic device 1, the guiding rail 130 slides to the receiving position R. The cover 140 is rotated to the closing state for closing the insertion hole 910. At this point, the electronic device 1 remains the original appearance, and the insertion hole 910 is closed by the cover 140, protecting the electrical connection socket 110.

Furthermore, the whole structure of the card reader is disposed close to an inner wall surface of the case body 900 without reserving a space for inserting the electronic card 800 to the interior of the case body 900, and still has the function of guiding the electronic card 800 to be connected to the electrical connection socket 110, while reducing the space occupied by the card reader 100.

Please refer to FIG. 2, FIG. 3, FIG. 6 and FIG. 8, in which when the electronic card 800 is inserted into the electronic device 1, the cover 140 is firstly rotated to the opening state for opening the insertion hole 910. Then, a user pulls the cover 140 outwards or directly pulls the guiding rail 130, and the guiding rail 130 moves to the card insertion position I.

Next, the user aligns the electronic card 800 with the insertion hole 910 to make the edge of the electronic card 800 leans on the guiding rail 130 to guide the electronic card 800 with the guiding rail 130. Finally, under the guidance of the guiding rail 130, the electrical connector 810 of the electronic card 800 is inserted into the electrical connection socket 110. Meanwhile, one side edge or two side edges of the electronic card 800 are supported by the guiding rail 130.

Please refer to FIG. 9 and FIG. 10, in which a card reader 100 having a movable card insertion structure according to a second embodiment is disclosed.

In the second embodiment, the card reader 100 includes an electrical connection socket 110, two guiding members 120, a guiding rail 130, and a cover 140. The electrical connection socket 110, the two guiding members 120 and the cover 140 are substantially the same as those of the first embodiment.

As shown in FIG. 9 and FIG. 10, the guiding rail 130 includes two sliding portions 131 and a lower support portion 132.

The two sliding portions 131 are respectively disposed in two guiding slots 129 in a slidable manner. The lower support portion 132 connects the two sliding portions 131. The lower support portion 132 presses against the bottom surface of the electronic card 800 with a relatively large contact area, so as to provide a relatively large supporting force for the electronic card 800. The lower support portion 132 in the second embodiment further facilitates guiding the electronic card 800 to pass through the insertion hole 910 and enter into the case body 900.
